Monthly Business Expense Calculator

Itemize recurring monthly business expenses across facilities, payroll, technology, marketing, insurance, and administrative supplies to identify major cost drivers.

7-Pillar Monthly Expense Inputs

Monthly Expense Aggregation Formula

Monthly Total = Facilities + Payroll + Tech SaaS + Marketing + Insurance + Admin Supplies + Contingency; Annual Run Rate = Monthly Total × 12
  • Category Distribution: Compares each expenditure against the total monthly budget to expose operational bloat.
  • Daily Burn Rate: Average cash required per calendar day to keep the enterprise open and operational.

Step-by-Step Worked Example

Scenario: A mid-size firm with $25,000 in monthly expenses across 7 cost divisions

Calculation Steps:

  1. Total Monthly Expenses = $3,500 + $15,000 + $1,200 + $3,000 + $1,000 + $500 + $800 = $25,000
  2. Annual Run Rate = $25,000 × 12 = $300,000 / year
  3. Daily Burn Rate = $25,000 / 30.42 days = $821.92 / day
  4. Largest Expense Category = Payroll & Contractors (60.0% of total budget)
Result: Total monthly business expenses are $25,000 ($300,000 annual run rate, $822/day burn), with Payroll being the primary driver at 60.0%.
